I have a new HP 2215 and a Sandisk SD WiFi card. The installation of the card went great. The problem I'm having is getting the card to recongize my wireless network at home. I don't know if its the wireless router or settings on the iPAQ 2215. Please help!

I guess I'm just dumb on this (Lack of wireless and Network training) I'm using a iPAQ 2215 with a sandisk sd card. The main computer is Windows XP and a D-Link Wireless router model DI-514. I went to a local truckstop that has Wifi. My iPaq picked it right up. It wouldn't let me dload because I don't have an account. It said unable to load page. At home it won't even see the router. What a mess. Any hlep would be great as this is my second wireless card for this IPAQ. Thanks
